There is actually the previous Bug#203668 Not sure if this is discontinued as a separate port.
Nope, this isn't discontinued. GH/ipython/ipykernel depends on it And jupyter-qtconsole depends on GH/ipython/ipykernel.
(In reply to yuri from comment #2) Since the notebook parts have been moved to Jupyter, what else would be needed to get all the current features back? Would you be able to look into the missing ports?
I have all ports for the whole Jupiter stack working. However, almost all notebooks fail due to the fortran problem. Fortran can't be executed together with other C++ code because of the libgcc.so conflict. gcc builds its own incompatible libgcc.so. I am currently looking into the ways to solve this. Possible ways are to build libgfortran.so from gcc source tree with clang, or to replace base libgcc.so with libunwind (exists in ports).
Closing PR as devel/ipython is now up to date.
